NVIDIA plans to reveal its GeForce 7800 GTX with 512MB of memory On November 7th and this card won’t have different clock speeds from its 256MB version but this could easily change. NVIDIA knows that ATI will be one or even two weeks late with the Radeon X1800XT as we don’t expect to see any cards before the twenty something of November and NVIDIA will be there to nail ATI with its 512 MB cards. GeForce 7800 GTX 512 MB cards are again going to be available at launch, and it’s very likely that they will also be cheaper than ATI’s Radeon X1800XT cards.
